Update CloudWatch plugin's required IAM permissions

[adis-io]

Without this policy it won't be possible to use custom retention period

@adis-io do you have a valid test case for this? or a reference from the Cloudwatch's docs?

No, I don't have test case, I've just had this issue in my case

From AWS Docs:

When you create a log group, by default the log events in the log group do not expire. To set a retention policy so that events expire and are deleted after a specified time, use PutRetentionPolicy .
